The ATMEGA32U4-MU is an 8-bit AVR microcontroller manufactured by Microchip Technology. This surface-mount device integrates a high-performance AVR core capable of running at up to 16MHz, along with 32KB of in-system self-programmable flash memory, 2.5KB of SRAM, and 1KB of EEPROM. It is housed in a 44-VFQFN exposed pad package (44-VQFN 7x7) and operates over a supply voltage range of 2.7V to 5.5V.
Connectivity options include I2C, SPI, UART/USART, and USB 2.0, making it suitable for a wide range of embedded applications. The microcontroller provides 26 I/O lines, a 12-channel 10-bit ADC, and peripherals such as brown-out detection, power-on reset, PWM, and a watchdog timer. Its internal oscillator simplifies circuit design by eliminating external clock components.
With an operating temperature range of -40°C to 85°C, the device is qualified for industrial environments. The compact 7x7mm VQFN package is ideal for space-constrained PCB layouts, while the integrated USB interface enables direct connection to host systems without additional glue logic.
